Firstly, the music videos feature clips from throughout the main show. Music is alright for what it is. Nothing to write home about. They're only short, and it didn't hurt.
The 3 shorts were okay. Artwork was less refined than in main show (where I didn't it was particularly wonderful either) but overall, all 3 are sweet little bits of filler. I didn't rate them very high as they were a bit too short and the artwork . They all sufficed as extras though. First episode does include something that appears in the main show
All 6 take just under 13 minutes. You may as well watch them if you watched the main show.
